NOTE:
If this saw is to be used for commer-
cial logging, a chain brake is required and
shall not be removed or otherwise disabled
to comply with Federal OSHA Regulations
for Commercial Logging.
SAFETY NOTICE:
Exposure to vibrations
through prolonged use of gasoline powered
hand tools could cause blood vessel or nerve
damage in the fingers, hands, and joints of
people prone to circulation disorders or
abnormal swellings. Prolonged use in cold
weather has been linked to blood vessel
damage in otherwise healthy people. If
symptoms occur such as numbness, pain,
loss of strength, change in skin color or texture,
or loss of feeling in the fingers, hands, or joints,
discontinue the use of this tool and seek
medical attention. An anti-vibration system
does not guarantee the avoidance of these
problems. Users who operate power tools on
a continual and regular basis must monitor
closely their physical condition and the
condition of this tool.
SPECIAL NOTICE:
Your saw is equipped
with a temperature limiting muffler and spark
arresting
screen
which
meets
the
requirements of California Codes 4442 and
4443. All U.S. forest land and the states of
California, Idaho, Maine, Minnesota, New
Jersey, Oregon, and Washington require by
law that many internal combustion engines
to be equipped with a spark arresting screen.
If you operate a chain saw in a state or locale
where such regulations exist, you are legally
responsible for maintaining the operating
condition of these parts. Failure to do so is
a violation of the law. Refer to the SERVICE
section for maintenance of the spark
arresting screen.
Failure to follow all Safety Rules and Precau-
tions can result in serious injury. If situations
occur which are not covered in this manual,
use care and good judgement. If you need
assistance, contact your authorized service
dealer or call 1-800--554--6723.

3. An adjusting pin and screw is used to ad-
just the tension of the chain. It is very im-
portant when assembling the bar, that the
pin located on the adjusting screw aligns
into a hole in the bar. Turning the screw will
move the adjustment pin up and down the
screw. Locate this adjustment before you
begin mounting the bar onto the saw. See
illustration below.
